SRM16-12 inflatable SF6 metal enclosed fully insulated series ring network switchgear is widely used in 10kV/6K distribution systems and is the preferred switch product for various urban and rural user transformation and distribution systems. The switchgear adopts a modular unit mode, which can be combined according to different purposes; It consists of two categories: fixed unit combinations and expandable units, meeting the flexible use needs of various substations for compact switchgear.
SRM16-12 inflatable switchgear is a completely sealed system, with all live parts and switches enclosed in a stainless steel casing. The entire switching device is not affected by external environmental conditions, thus ensuring operational reliability and personal safety, and achieving maintenance free. By selecting expandable busbars, any combination can be achieved, achieving full modularity. The expansion of busbar safety insulation and shielding ensures high reliability and safety. The SRM16-12 inflatable switchgear can also provide TV based automation solutions, forming the concept of intelligent switches and minimizing on-site installation and debugging workload.
SRM16-12 inflatable switchgear is divided into non expandable standard configuration and expandable standard configuration. Due to its combination of full module and half module, as well as its own scalability, it has extremely special flexibility.
The SRM16-12 inflatable switch complies with the GB standard. The design lifespan for operation under indoor conditions (40 ℃) and outdoor conditions (-50 ℃) exceeds 30 years.
